The rubber components on the Freeze Dryer may eventually deteriorate and 
require replacement.  The effective life of rubber parts depends upon both their 
usage and the surrounding environment.  Check all rubber hoses and gaskets 
and replace any that show signs of hardening, permanent set or deterioration. 

2.

 

Using a soft cloth, sponge or chamois and a mild, non-abrasive soap or 
detergent, clean the acrylic chamber lid. 

3.

 

Using a soft cloth, sponge, or chamois and a mild, non-abrasive soap or 
detergent, clean the exterior surfaces of the Freeze Dryer.  Liquid spray 
cleaners and polishes may be used on the exterior surfaces.  Do not use 
solvents to remove stains from the exterior surfaces as they may damage the 
finish. 

 

Annually: 

 
1.

 

Every 12 months, or more often if the Freeze Dryer is operated in a dusty 
environment, the refrigeration system condenser should be cleaned.  Using a 
vacuum cleaner with brush attachment, clean the condenser to ensure proper 
airflow for peak performance. 

 

Front Access Panel Removal (Console Models) 

 
The front stainless steel panel can be removed by placing a flat blade screwdriver 
in the rectangular hole in the center of the kick panel.  Pivot the handle downward 
to disengage the latch and simultaneously pull the bottom edge of the lower panel 
forward.  The lower panel is installed by first sliding the top edge under the lip on 
the plastic control panel.  Pivot the bottom inward and push until the latch is 
secure.
